Process pressures p1 und p2 are applied to the media
chambers ⊖ (2) and ⊕ (3).
■ Measuring cell (4) is filled with transmission liquid.
■ Differential pressure across ⊕ and ⊖ pressure sides deflects
the diaphragm (1) and displaces the transmission fluid.
■ The deflection of the connection rod (5) is converted through
the use of a transmitting lever (6) into rotation, which is transfered
over an axial shaft (7) to the movement (9).
■ The torque pipe (8) seals, assuring a frictionless path from the
measuring cell.
■ Overpressure protection in both directions up to the max. total
pressure applied is provided by contoured metal bolsters.
